Im looking for help with trying to vary a variable-name in a for loop:
For b = 1 To Count
' the below image_var(b) varible needs to vary on each iteration'
Dim image_var(b) As New LinkedResource(Server.MapPath(myArray(b-1)))
' need also to have the b in myArray(b-1) bit work through the loop too'
' that is I''m after the array index b minus 1'
image_var(b).ContentId = "imageContentId_" + b.ToString

i have a program that is going to be disabling services depending on what is selected by the user via check boxes, and it would also add to the log if it failed or succeed ( the dim xfailed as integer ). There are a total of 73 options for services and i didn't feel like copy and pasting IF THEN statements for all 73. I was wondering if i could make a loop out of this?
The x would be the service name - ex. "Themes"
Dim x as serviceprocess.servicecontroller = new serviceprocess.servicecontroller(x)
dim xFailed as integer

The subject almost sums this up. I have dimensioned a variable 'y' inside a for loop. If i then try and access this outside of the for loop I cannot. What is the reason for this and how can I correct it? Unfortunately I am not able to Dim the variable 'y' outside of the for loop.

Is it possible to define two variables in a vb2005 For loop in a similar way that jscript does it?
the javascript example is
for(i=0,l=0;i<20;i++){}
Using VB.NET .NetFramwork 3.5. This fails and strikes me as odd. Is this correct behavior:
Public Sub TestForEach()
For index As Integer = 1 To 10
Dim z As Integer
Assert.AreEqual(0, z)
z = index
Next
End Sub
I would expect z to always equal 0 as I thought the dim-ing of an integer would set the value to 0. If you run this. It fails at the second loop. For some reason z retains it's value of 1. I know I can manually initialize z to = 0, but I wanted to know if this is a bug or expected behavior.

I'm multiplying X*Y*Z in a loop of 200 interations Y is declared as a constant. A timer can cause the loop to pause for 10 seconds.
During this 10 sexond pause I would like to change the value of Y. It needs to be changed only for this run, not a permanent change which can be done in the declaration.
wondering about the relatively efficiency of declaring oop variables in the loops, emselves, or declaring them before first use. Here are some examples:Declare early:
Dim ix As Integer
Dim currentNode As System.Xml.XmlNode
For ix = 1 To 100
[code].....
For i As Integer = 1 To 10
Dim j As Integer = 10
Next
now my question is, Is memory allocated to j every time its executed inside for loop? or only value of 10 is assigned on subsequent iterations?
I am trying to insert a string variable inside of two strings, and make a combined string. Public Sub Page_Load() Dim Id As String Id = Trim (Request.QueryString("Id")) End Sub Dim mp3text as string url... & Id & ".mp3" My goal is to make the mp3text variable have a string that is: url...(If Id is 7) It is for some reason not connecting up correctly. I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
View 12 Replieshow to "loop through a datagrid column to add values to a variable
in VB6 it was something like:
do while not .eof
myvariable = myvariable + datagrid1.collumns(6)
loop
Lets say I have declared an array by doing:
dim array()
Also have a variable:
dim loopsize = 10
Then i do this:
for loop = 1 to loopsize
array(loop) = 5
next
What i wanted to do with this is from array(1) through to array(10), the values will be changed to 5. But vb will not allow this and crashes.
Why doesn't this work and how can i make it work?

OK, after trying to get this working for a couple of days now I decided that I would turn to the experts here. I am trying to create a nested loop with a variable amount of nests. Let me elaborate. I have a program that first asks for the minimum and maximum amount of loops, I currently have a SELECT CASE statement that addresses each level of nesting individually.

I'm trying to use the timer (not a Timer object) in a Do... Until loop. I want the loop to put a single variable into a label. When I do this it works and puts the value into the label (lblOxygenReading):
If btnGetOxygen.Text = "Get Oxygen Reading" Then
Select Case True
Case rdoColorWhite.Checked
strCurrentColor = "White"
Case rdoColorRed.Checked
[Code] .....
It goes through the Do loop and the For.. next loop but doesn't change the label. Visual Studio doesn't show any errors when I'm writing the code, but when I run it, it hangs somewhere.
The code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

I have a List(of String()). I have written a custom comparer (implements IComparer(of string)) to do an alphanumeric sort.Is there a way to sort the List using a given index to determine which position in the String() to sort by? In other words one time I might sort by Index = 0 and another time by Index = 3. The length of all String() in the list is the same.For reference this question is similar to Sort List<String[]> except I am using VB.net and that question is hardwired to Index=0.
EDIT from OP's comments:I started simple with the non custom comparer but I am getting an error: expression does not produce a value. Not sure what I am doing wrong.Here is the code:
Public Shared Function SortListOfStringArray(ByVal ListOfStringArray As List(Of String()), ByVal SortByIndex As Integer) As List(Of String())
Return ListOfStringArray.Sort(Function(x, y) x(SortByIndex).CompareTo(y(SortByIndex)))
End Function
